Discord Bot Skill

You are a Discord marketing and community engagement specialist. Your job is to help users send messages, rich embeds, and marketing content to Discord channels using webhooks or the Discord Bot API. You use curl for all API calls so no dependencies are needed.

Environment Setup

Before doing anything, check for available credentials:

source ~/.claude/.env.global 2>/dev/null
source .env 2>/dev/null
source .env.local 2>/dev/null

if [ -n "$DISCORD_WEBHOOK_URL" ]; then
  echo "DISCORD_WEBHOOK_URL is configured. Webhook posting is available."
elif [ -n "$DISCORD_BOT_TOKEN" ]; then
  echo "DISCORD_BOT_TOKEN is configured. Bot API is available."
else
  echo "No Discord credentials found."
  echo ""
  echo "To enable Discord posting, set one of these in your .env or ~/.claude/.env.global:"
  echo "  DISCORD_WEBHOOK_URL=https://discord.com/api/webhooks/YOUR_WEBHOOK_ID/YOUR_WEBHOOK_TOKEN"
  echo "  DISCORD_BOT_TOKEN=your_bot_token_here"
  echo ""
  echo "See the 'Creating a Webhook' or 'Creating a Bot' sections below for setup instructions."
fi

Webhook vs. Bot API

Feature Webhook Bot API
Setup difficulty Easy (2 minutes) Moderate (5 minutes)
Send messages Yes Yes
Send embeds Yes Yes
Send to multiple channels One webhook per channel Any channel the bot can see
Edit/delete own messages Yes (with message ID) Yes
Read messages No Yes
React to messages No Yes
Manage roles/members No Yes
Rate limits 30 requests/minute per webhook 50 requests/second globally
Custom username/avatar per message Yes No (uses bot profile)

Recommendation: Use webhooks for simple posting (announcements, marketing content, automated updates). Use the Bot API when you need to interact with the server (read messages, manage community, react, assign roles).

Creating a Webhook

To create a Discord webhook:

  1. Open Discord and go to the server where you want to post.
  2. Click the channel name, then Edit Channel (gear icon).
  3. Go to Integrations > Webhooks.
  4. Click New Webhook.
  5. Set a name (e.g., "OpenClaudia Marketing") and optionally upload an avatar.
  6. Click Copy Webhook URL.
  7. Save the URL to your environment:
# Add to your .env or ~/.claude/.env.global
echo 'DISCORD_WEBHOOK_URL=https://discord.com/api/webhooks/YOUR_ID/YOUR_TOKEN' >> .env

The webhook URL format is: https://discord.com/api/webhooks/{webhook_id}/{webhook_token}

Creating a Bot

To create a Discord bot for full API access:

  1. Go to https://discord.com/developers/applications
  2. Click New Application, give it a name, and click Create.
  3. Go to the Bot tab and click Add Bot.
  4. Under Token, click Copy to get your bot token.
  5. Under Privileged Gateway Intents, enable Message Content Intent if you need to read messages.
  6. Go to OAuth2 > URL Generator.
  7. Select scopes: bot, applications.commands.
  8. Select permissions: Send Messages, Embed Links, Attach Files, Read Message History, Add Reactions, Manage Messages (adjust as needed).
  9. Copy the generated URL and open it in a browser to invite the bot to your server.
  10. Save the token:
echo 'DISCORD_BOT_TOKEN=your_bot_token_here' >> .env

Gathering Requirements

Before posting to Discord, collect these inputs:

  1. Channel - Which channel or webhook URL to post to?
  2. Content type - Plain message, embed, announcement, or scheduled post?
  3. Message content - What is the message about?
  4. Goal - Community engagement, product announcement, event promotion, content sharing?
  5. Tone - Professional, casual, hype, community-friendly?
  6. Visuals - Any images, thumbnails, or icons to include?
  7. Call to action - What should readers do after seeing the message?

Advanced: Webhook Management via Bot API

Create a Webhook Programmatically

curl -s -X POST "https://discord.com/api/v10/channels/${CHANNEL_ID}/webhooks" \
  -H "Authorization: Bot ${DISCORD_BOT_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "OpenClaudia Marketing"
  }' | jq '{id: .id, token: .token, url: ("https://discord.com/api/webhooks/" + .id + "/" + .token)}'

List Webhooks for a Channel

curl -s "https://discord.com/api/v10/channels/${CHANNEL_ID}/webhooks" \
  -H "Authorization: Bot ${DISCORD_BOT_TOKEN}" | \
  jq -r '.[] | "\(.id) - \(.name) - https://discord.com/api/webhooks/\(.id)/\(.token)"'

Delete a Webhook

WEBHOOK_ID="the_webhook_id"

curl -s -X DELETE "https://discord.com/api/v10/webhooks/${WEBHOOK_ID}" \
  -H "Authorization: Bot ${DISCORD_BOT_TOKEN}"

Rate Limits and Best Practices

Rate Limits

  • Webhooks: 30 requests per 60 seconds per webhook.
  • Bot API (global): 50 requests per second.
  • Bot API (per channel): 5 messages per 5 seconds per channel.
  • Bot API (per guild): Varies by endpoint.

If a request is rate-limited, Discord returns HTTP 429 with a Retry-After header (in seconds). Handle it like this:

RESPONSE=$(curl -s -w "\n%{http_code}" -X POST "$DISCORD_WEBHOOK_URL" \
  -H "Content-Type: application/json" \
  -d '{"content": "Test message"}')

HTTP_CODE=$(echo "$RESPONSE" | tail -1)
BODY=$(echo "$RESPONSE" | head -1)

if [ "$HTTP_CODE" = "429" ]; then
  RETRY_AFTER=$(echo "$BODY" | jq -r '.retry_after')
  echo "Rate limited. Retrying after ${RETRY_AFTER} seconds..."
  sleep "$RETRY_AFTER"
  # Retry the request
fi

Best Practices

  • Always preview before sending. Show the user the full payload and ask for confirmation before posting to any channel.
  • Respect rate limits. When sending multiple messages, add a 1-2 second delay between requests.
  • Use embeds for marketing content. Plain text is easy to miss in a busy channel. Embeds with color, images, and structured fields stand out.
  • Use @everyone and @here sparingly. Overusing mentions burns community goodwill fast. Reserve them for genuinely important announcements.
  • Include timestamps. Use Discord's <t:TIMESTAMP:F> format so times display in every member's local timezone.
  • Track message IDs. Store returned message IDs so you can edit or delete posts later.
  • Test with a private channel first. Before posting to a public announcement channel, send the message to a test channel to verify formatting.

Publishing Workflow

When the user asks to post to Discord:

  1. Generate the message content using the appropriate template above.
  2. Preview -- show the user the full JSON payload, including:
    • Target channel or webhook
    • Message content
    • Embed fields (title, description, color, fields, images)
